Cooling & Heating System for Chemical Reactor

From the practical point of view of chemical production, as the core control part of the production system, reactor temperature control plays an important role. Because the reaction link in the reactor will absorb and release heat, it has time-varying and nonlinear characteristics, which increases the difficulty of temperature control. Currently, adaptive PID cooling & heating systems are mostly used to enhance the temperature control effect.

The reactor used in chemical production is the main reaction vessel. The heat-conducting medium of the mold temperature machine is used to heat the material with the help of a jacket. Generally speaking, heat transfer media such as water and thermal oil are commonly used. From the perspective of the reaction process, it mainly includes a heating section, a constant temperature section and a cooling section. Among them, the constant temperature section is the key.

Chemical production is complex and refined processing, and it is difficult to control the heating temperature during the processing process. This is because the physical quantity of temperature is easily affected by the surrounding environment. It not only has inertia but also has hysteresis and other characteristics, and the system response speed is relatively slow.

The traditional temperature control uses the traditional PID algorithm, which is difficult to achieve effective control effects. After continuous optimization and improvement, adaptive fuzzy PID control technology is applied, and the adaptive fuzzy PID cooling & heating system is used to adjust the PID parameters online. Achieve effective control of temperature.

In terms of practical application effects, the adaptive fuzzy PID cooling & heating system is used to control the reactor temperature. The parameters can be optimized and adjusted based on the actual changes in the system deviation and deviation change rate. It has good adaptability and can achieve High-precision control of reactor temperature.
